RT Journal Article SR Electronic T1 Carbon Pneumoconiosis in a Synthetic Graphite Worker JF British Journal of Industrial Medicine JO Br J Ind Med FD BMJ Publishing Group Ltd SP 114 OP 116 DO 10.1136/oem.18.2.114 VO 18 IS 2 A1 Lister, W. B. YR 1961 UL http://oem.bmj.com/content/18/2/114.abstract AB A case of carbon pneumoconiosis is described and discussed. A man, aged 60, who had been turning and grinding synthetic graphite bars for 17 years, developed pneumoconiosis, Category 3. In conjunction with others previously published, this case confirms that pneumoconiosis can be caused by “nearly pure” carbon of low ash content and a wide range of particle size after long exposure to synthetic graphite or carbon black dust.
